Hello everybody !

I created a (very) little plugin for my Mat 1.2, following the tutorial :
h_t_t_p_:_/_/wiki.eclipse.org/MemoryAnalyzer/Extending_Memory_Analyzer#Setting_up_a_development_environment_for_writing_extensions

It works fine when I start Mat from my Eclise project throught Plug-in, Run As->Eclipse Application

But once I have packaged my plugin and tried to deploy it :
File->Export->Plug-in Development->Deployable plug-ins and fragments
->next
select plug-in
Destination: Directory: path_to_MAT/mat
->Finish

then my plugin is not loaded.
I find it (MAT_wM_Extension_1.0.0.201205092200.jar) in path_to_MAT/mat/plugins, but it is not it the list in help->About Eclipse Memory Analyzer->Installation details->plug-ins
(when mat is started with my Eclipe project, then it is in the list)

My plugin is wery simple, and only contains a nameResolver and a void query.

I joined it.

I have been stuck for two days, and do not understand was is happening.

Then I will be glad for any answer/help.
Thanks !

Either create an update site and install that, or create a dropins directory under mat/ and put your plug-in there, then see https://bugs.eclipse.org/bugs/show_bug.cgi?id=320082#c19 for how to use the dropins folder.

Dear Andrew,
thank you so much for your answer !

Unfortunately, I have not been able to understand what to do, even with the help of the link you provided. Sad

I am not even sure that my jar file has a correct structure.

I spent too much time on this, I quit.

It is very disappointing that with all the great work that has been done on this kind of tools, there is no complete howto or wiki giving correct instructions that actualy work, and that could be usable by any ordinary java developper and not only Eclipse hackers.

Thanks a lot for your time and answer Andrew.
